Error Mounting Proc Bus Usb Ubuntu
15" Bootup Problem After Failed Upgrade to GRUB 2? Boot Ubuntu with Super GrubDisk! » Fix "An error occurred while mounting /proc/bus/usb" Bootup Error after Upgrade toLucid May 7, 2010 by Ubuntu Genius An error occurred while mounting /proc/bus/usb. Press S to skip mounting or M for manual recovery. If you're getting this at boot, it is probably a left-over from forcing USB support in VirtualBox in Karmic and before. In Lucid Lynx 10.04, this line is no longer needed, and in fact causes this minor error - though, in some cases, it is actually rendering the system unbootable. The solution is actually very simple and easy to implement, and merely requires removing or commenting out a line in the fstab file. To do so, open a terminal and enter: sudo gedit /etc/fstab Find the line "none /proc/bus/usb usbfs devgid=125,devmode=664 0 0" and either remove it or add a hash (#) to the beginning of the line to turn it into a harmless comment. If you are in the worst case scenario and can't get to your desktop at all, then at the command-line (which you can get to in Recovery mode) you'll have to open fstab in a CLI-based text editor like nano with the command: sudo nano /etc/fstab (If using nano, Ctrl+X to exit, Y to confirm saving the changes, leaving the file name as "fstab", then press Enter) That's it - your system should now boot fine. ☻☻☻☻☻☻☻☻☻☻☻☻☻☻☻☻☻☻☻☻☻☻☻☻☻☻☻☻☻☻☻☻☻☻☻☻☻☻☻☻☻☻☻ Did this information make your day?

Most users only started getting this message after upgrading to Lucid Lynx, and for everyone removing that line fixed that issue… without affecting USB support in Virtualbox, since the support doesn't need to be forced anymore. If you are running 10.04, make sure you have the latest (or most compatible) version of Virtualbox. on May 13, 2010 at 4:25 am | Reply Wall-e I have Ubuntu 10.0

I could not find the usb/devices file in default path, which is: /proc/bus/usb/devices 13.04 usbfs share|improve this question asked Jul 30 '13 at 17:13 Binoy Babu 3211412 add a comment| 2 Answers 2 active oldest votes up vote 4 down vote Not available in the current versions of Ubuntu Usbfs has been deprecated http://askubuntu.com/questions/326597/enabling-usbfs-in-ubuntu for a long time already. It was disabled since Ubuntu 9.10 (but you could recompile the kernel to get it -- CONFIG_USB_DEVICEFS=y). In the Linux kernel it was completely removed in 3.5 so it is completely missing since Ubuntu 12.10. So the bad news is that you cannot enable usbfs in Ubuntu 13.04 if you do not replace the kernel for an older or patched one. Alternate solution It seems that the similar content as was in /proc/bus/usb/devices is now available in /sys/kernel/debug/usb/devices. Other interesting places to check for the content from former usbfs are: /dev/bus/usb, /sys/bus/usb and /sys/kernel/debug/usb.

Just press Ctrl+Alt+T on your keyboard to open Terminal. When it opens, run the command(s) below: sudo mount -t usbfs none /proc/bus/usb -o devmode=0666 share|improve this answer answered Jul 30 '13 at 17:22 Mitch♦ 64.2k12130183 1 Since Ubuntu 9.10 the mount point /proc/bus/usb does not exist because usbfs is not enabled in the kernel. Since Linux kernel 3.5 (Ubuntu 12.10) usbfs is missing completely. –pabouk Dec 8 '13 at 21:55 add a comment| Your Ans

Also affects distribution/package Nominate for series Bug Description Binary package hint: util-linux If a system that has a /etc/fstab entry that contains a usbfs entry is booted in 10.04 then this error will appear (and I believe it could interrupt the booting process). The workaround is simple, comment out or remove the offending line error mounting proc in /etc/fstab, but unfortunately a lot of system that are being upgraded have entries like this left in the file and then have this error. If the mount process not longer supports this filesystem type, then it should just ignore it and place a message in the syslog file.

02/05/2010 - 22:35 Instalación y actualizacionesPues eso he actualizado y cuando entro en la pantalla de inico me sale este mensaje "An error occurred while mounting /proc/bus/usb" y me da la opción de skip o manual recovery". Si le doy a la opción de skip entro normalmente, si le doy a manual recovery entro en modo consola y no se como actuar. Me podeis ayudar a que no me salga ese mensaje y entrar normalmente. Por lo demas todo perfecto. Un saludo.

Alomejor es algo residual que tenemos los que nos hemos actualizado desde versiones anteriores, no lo sé. Sólo sé lo que falta: 1- Abre un terminal (Aplicaciones > accesorios > Terminal) 2- Escribe "sudo nano /etc/fstab" y escribe la contraseña cuando te la pida. 3- Una vez abierto el archivo, localiza la línea "none /proc/bus/usb usbfs devgid=123,devmode=644 0 0", que creo que es la última, y añádele delante una "#". 4- Pulsa "Ctrl" + "X" para salir. 5- Te pedirá que confirmes el guardado, pulsa "Y". 6- Te pedirá un nombre de archivo, por defecto "fstab", déjalo como está y pulsa "Enter" para terminar. Esa es la solución! :P Si queréis comprobar que funciona, escribid "sudo reboot" para reiniciar, ya veréis como no os vuelve a aparecer el problema. Un saludo y espero que sirva de ayuda. -Alex- (alejandronumerouno) +1 0 -1 Inicie sesión o regístrese para comentar +1 0 -1 Gracias muy amable.

Eso no resuelve el problema. Sirve para evitar que salga el mensaje de error, pero el verdadero problema es que el sistema no consigue montar los dispositivos USB para que puedan ser usados en las máquinas virtuales.
